No-Ammonia: Add one tsp of No-ammonia solution per 10 gallon of water to remove toxic ammonia.
Sodium Thiosulfate: This is the active ingredient that removes chlorine found in a large number of chorine removal products. So, if all you need is cheap chlorine removal, this is the product to use. It can be overdosed without harm. In fact, it is a very effective Redox Reducer, eliminating oxidizing free radicals from the water. Overdosing is actually a good thing. Does not remove chloramines. If you have chloramines, it will break the chlorine/ammonia bond, leaving the ammonia to be handled by your bio filter.
